My Eclipse workspace is set to UTF-8 as is my OS (Linux). When I open a file that is asccii encoded and contains extended ascii characters that are invalid utf-8, Eclipse gives no warning. When I save the file, Eclipse saves as utf-8 and replaces all invalid utf-8 character with the (valid) utf-8 character U+FFFD (displayed as �, hex EF BF BD).
I'd agree that the source file should not be asccii in the first place, still I'd like Eclipse to give a warning when opening a file that is invalid utf-8. Is there a setting in Eclipse to make it behave that way?
I am using Eclipe Kepler version 4.3.1 with PDT extension version 3.2.0
